Method Detail

getByteLength

public int getByteLength()

Specified by:

getByteLength in interface Shape

Returns:

the number of bytes necessary to write this instance.

readPolyline

protected int readPolyline(byte[] bytes,
                           int offset)

readPolylineZ

protected int readPolylineZ(byte[] bytes,
                            int offset)

readPolylineM

protected int readPolylineM(byte[] bytes,
                            int offset)

read

public int read(byte[] bytes,
                int offset)

Description copied from interface: Shape

Reads the object from a byte array.

Specified by:

read in interface Shape

offset - where to start reading

Returns:

the new offset or -1, if the type was wrong.

writePolyline

protected int writePolyline(byte[] bytes,
                            int offset)

writePolylineZ

protected int writePolylineZ(byte[] bytes,
                             int offset)

writePolylineM

protected int writePolylineM(byte[] bytes,
                             int offset)

write

public int write(byte[] bytes,
                 int offset)

Description copied from interface: Shape

Writes the object to a byte array.

Specified by:

write in interface Shape

Returns:

the new offset.

getType

public int getType()

Specified by:

getType in interface Shape

Returns:

the type of the shape

getEnvelope

public ShapeEnvelope getEnvelope()

Specified by:

getEnvelope in interface Shape

Returns:

the shapes' envelope, or null, if it has none

getGeometry

public Geometry getGeometry()
                     throws ShapeGeometryException

This creates a MultiCurve object.

Specified by:

getGeometry in interface Shape

Returns:

the shape as deegree Geometry

Throws:

ShapeGeometryException - if the deegree geometry could not be constructed
